    摘要： Poly-(caffeyl alcohol) (PCFA), also known as C-lignin, is a promising new source of both carbon fibers and pure carbon. PCFA can be used to produce carbon fibers by direct electrospinning, without blending with another polymer to reduce breakage. Analyses have shown that the carbon obtained from PCFA is superior to that obtained from other lignins. The fibers formed from PCFA are smoother, have a narrower diameter distribution, and show very low defects. The PCFA can be obtained by extraction from plant seed coats. Examples of these plants include the vanilla orchid, Vanilla planifolia, and Jatropha curcas. The fibers may be formed through electrospinning, although other methods for forming the fibers, such as extrusion with a carrier polymer, could be used. The fibers may then be carbonized to increase the carbon yield.

    摘要： The present invention relates to an electrospinning device for manufacturing a nanofiber, and the purpose of the present invention is to provide an electrospinning device for manufacturing a nanofiber, wherein a substrate is transferred while a nanofiber web is stacked and formed on a side surface of the substrate through electrospinning of a polymer spinning solution, and the substrate is rotated during transfer such that the nanofiber web is stacked and formed on the other side surface; accordingly, the nanofiber web can be stacked and formed on both surfaces of the substrate through a single manufacturing process; a drying process is performed simultaneously during rotation of the substrate such that, at the same time the nanofiber web is stacked on both surfaces of the substrate, the substrate is dried through a single manufacturing process, thereby removing any solvent remaining on the nanofiber web; and, as electrospinning devices, electro-blown electrospinning devices and electro-spinning electrospinning devices are installed alternately, such that electro-spinning electrospinning and electro-blown electrospinning can be performed alternately with regard to a transferred substrate.

    摘要： The purpose of the present invention is to provide an electrospinning device for manufacturing a nanofiber, the device comprising multiple units arranged successively, wherein units for ejecting a hot melt and units for ejecting a polymer spinning solution are installed alternately, the hot melt is ejected onto a substrate from nozzle blocks of the hot melt units positioned on the front end, and the polymer spinning solution is electrically spun onto the substrate, to which the hot melt has been ejected, from nozzle blocks of the spinning solution units positioned on the rear end, thereby stacking a nanofiber web. Accordingly, the nanofiber web can be easily attached to the substrate; the device is applicable both to an upward electrospinning device and a downward electrospinning device; the holt melt is not only ejected separately from the polymer spinning solution but also is repeatedly ejected to specific areas and parts on the substrate, thereby substantially reducing use of the hot melt; interference of the hot melt with the nanofiber web is minimized concurrently with substantially reducing use of the hot melt, thereby improving the performance and quality of the nanofiber or the nanofiber filter; the hot melt can not only be ejected onto the substrate through each unit, but the same or different kinds of polymer spinning solutions can be electrically spun, thereby manufacturing various materials and kinds of nanofibers and nanofiber filters, and enabling mass production of nanofibers and nanofiber filters.
